How watch @observable in mobx-vue?

[snice]

export default class DatasourceViewModel {
 @observable public activePid: string = 'loading';
}

export default class Datasource extends Vue {
  @inject() public store: DatasourceViewModel;
  activePid: string = 'loading';
  $refs: {
    tableStruct: TableStruct,
    tableData: TableData,
  };
 //@Watch('store.activePid')
  @Watch('activePid')
  onActivePidChanged(val: string, oldVal: string) {
    this.$refs.tableStruct.packageId = val;
  }
}
